Cyclone Monica, a Category 5 cyclone on the Australian and Saffir-Simpson scales, threatens Australia's northern coast including the city of
Darwin. The Australian
Bureau of Meteorology has warned of "dangerously high tides" that may cause "extensive flooding" along part of the coast and ordered the sounding of emergency
sirens in the
Gove Peninsula.
Alcan, the world's second-biggest
aluminium producer, has warned customers of potential interruptions to supplies on contracts from its Gove refinery.
